Yes, gotta file. Undoubtedly several different errors involved in this one, yea olde 'chain of events'. Possibly a failure in the Risk assessment which no one who reviewed and signed it off noticed, maybe an additional equipment failure, possibly some one did something out of sequence which caused the whole thing to collapse (although that should have been identified and mitigated in the RA). In any case there will be a major engineering investigation but NATS is a 'no blame' company. Hhhhhmmm.

PS. As a customer, do we get any money back because NATS failed to meet the terms of our Contract or would such an outage be covered in any fault allowance?

just read that the outage caused less than 2000 minutes of delay - wow less than 33 hours. I know that this is total delays but I wonder how many flights are handled during the night in the scottish TMA and had such an incident happened inthe morning how much delay would have been caused.

This was a serious event. NATS spends a small fortune on making their power supplies uninterruptible and for such a failure to occur is alarming.
Sure it was planned maintenance and at a fairly quiet time but imagine if it had been a real power failure at LACC or LTCC on a Monday morning and the back-up hadn't worked.
I don't think it's a question of back to the drawing board but no matter what it costs it has to be sorted.

Cover-up by NATS?
I have to agree with Mr Jones.This was a very serious event, particularly for the operational staff who had the misfortune to be on duty at the time, and again, particularly for the ATCOs who were on radar when it all went blank.
It appears to me that NATS seem to be trying to dumb-down this incident and sweep it under the carpet. (Maybe tarnish their shiny new logo )
The NATS intranet site finally admitted to the incident two days after the event, and described it as a power interuption where a few systems were lost - no mention that these were live operational systems.
Also worthy of note was that the report only contained a few lines, and that the page counter showed that less than 100 people had viewed the page. Another (different) page also released onto the site that day had well over 1000 hits. So at what time on Friday was this page put up onto the intranet??? Maybe after most staff had gone home for the weekend?
Worse than Tony B and his "good day to hide bad news" methinks, or am I just TOO cynical?

... snip snip snip ....

Of course it could NEVER happen. Funny, is that not what was said the last time it 'never happened' .... but my memory is failing me ....... "nurse.. Nurse ... NURSE !! ... is it time for my pills again .. ?"
Well done to everyone who recovered from what might have been a very very bad situation. I think they should all get a huge Christmas bonus, a couple of days off in Lieu, and a public "thank you ". Thank goodness there was no outage of NAS planned ....
However, I would love to know the background of whoever put up the intranet statement that said "safety was never compromised".......... not that I am suggesting it was, but it is a rather pointless statement particularly if read by someone who has just heard the air conditioning go quiet ...
Hmmmm - if that's the case ... why don't we just get rid of radar and serviceable frequencies ... I mean do we REALLY need them, as they cost soooooooo much ..... ?
Until you've been there and had it all go 'plink' .. you have no idea ....

Chaos (?) In Scotland
Way back in 1973 when I did my Area Procedural Rating oral board exam, the last question I was asked by the Chairman (the famous Malcolm Lucas) was " why do we bother teaching this stuff when we're going for an all radar setup at the Centres ?" I said something along the lines of "because nobody believes Tels Engineers who say it'll never fail !" which caused some mirth on the Board.
As the French say (rough translation) " the more things change, the more they stay the same!"

Anyone remember the power failure at LATCC (yes - LATCC) in 91 or 92? That was a cracker, the room was only lit by the emergency comms panels and the glow of panicking ATCO's. Took hours to return to normal.

In Scottish 2 maybe 3 years ago when the same thing happened.......switched off mains to test standby..no problem..........switched off standby....oopps missed the page that said switch mains back on!!!!!!!!!
Could it be the engineers have those nasty channels back on the tele and have been making a mess of the manuals??????
ps.......sorry i missed that one, no power problems in the desert

It was a very serious event. Historically I do remember a JCB digging through the BT lines near Kilmarnock when ScACC/ScATCC(Mil) lost all radars and frequencies because BT failed to route the 2 feeds through different BT lines! In this instance the change from mains to standby power failed due to a faulty switch - which triggered a shutdown (a very non-technical statement!). The resultant loss of all radars and R/T can only be termed a catastrophic failure. When D and D were approached for possible use of 121.5 MHz to pass urgent messages to aircraft - D and D stated that all the emergency frequencies were also lost. As stated by someone earlier - if this had happened during the busiest part of the day, the results could have been a lot worse. It should always be the case that safety is paramount, and the availability of an assured source of power to radars and frequencies must be guaranteed.
